Steak Doneness Explained: Rare, Blue Rare, and Pittsburgh Variations

Steaks are one of the most delicious creations; it’s basically a piece of meat cooked in a certain way. Most people cook it in their own way; some like it with spices or sauce, and some like to season it just with salt. You may not know this, but the term steak goes way back to the 15th century in Scandinavia; people used to call a thick slice of meatsteik,’ a Norse word. While the term steak has Norse roots, it’s claimed that Italy can be the birthplace of steak.

Steak has become one of the most expensive dishes, as it should. Some people make it at home, while some go to restaurants, as there are many restaurants specifically for steak.

Steak can be made in numerous ways; you can get it cooked as rare, medium-rare, or well done. There are many other ways; people can’t differentiate between rare, Pittsburgh rare, and rare blue.

The term “Pittsburg rare” is used in most American Midwest and Eastern Seaboard, but the sear cooking methods of meat are known elsewhere as Chicago-style-rare, and in Pittsburg itself, it’s known as black or blue.

Why is a very rare steak called “Blue”?

Blue steak also goes with another term, which is extra rare steak. You must have an idea about blue rare steak by the term extra rare steak; nonetheless, let me elaborate. Blue rare steaks are lightly seared on the outside and are red from the inside. Their color gets purplish and bluish, as their name suggests. The steak is cooked for a short period of time; this way, it gets soft and tender from the inside, which is what most people prefer. The steak’s interior temperature shouldn’t exceed 115℉ to achieve the blue rare.
